3 be easily and quicklythrown out of the wind to stop further operation of the mechanism.

Still another object of this invention is the provision, in a manner as hereinafter set forth, of a wind mill of a construction whereby power may be transmitted directly to a vertical shaft and then to a horizontal shaft at the lower part of the mechanism from which horizontal shaft power may be taken to any desired point.

A further and final object of this invention is the provision, in a manner as hereinafter set forth, of a wind mill of novel construction, strong and durable, simple and inexpensive to construct.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawings but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressedin the a pp en de d claims.

In the drawings I Figure 1 shows the structure embodying this invention in side elevation. 7

Figure 2 is a section t-a'lren upon the line 22 of Figure 1.

Figure 8 is a section taken upon the line 33 of Figure 1.

Figure 4: is an enlarged detail of the frame.

Referring now to the drawings in detail wherein like numerals of reference indicate corresponding parts throughout the several views, the tower upon which the mechanism embodying this invention is mounted coinprises the usual uprightstandards 1, usually four in number and converging at their upper ends as shown. These uprights are braced and secured together by the cross braces 2.

At the upper end of the standards,there is mounted a head plate 3 having :1. depending Serial No. 50,475.

centrally apertured collar 4 which extends downwardly between the ends of the standards 1. Securing or brace bolts 5 are passed through the upper ends of the standards and secured in the collar t, and secured beneath the collar 4 and confined between the ends of the standards 1 is a second or brace collar 6 which also has secured thereinto the tie bolts 7 which pass through the standards and are secured thereto as shown.

The head plate 3 has formed in its upper surface a ball race in which ball bearings 8 are positioned, and supported upon these ball bearings is a centrally apertured revoluble table Qwhich has in its under surface a corresponding race way for the balls 8 to fit into.

Extending through the collars 4t and .6 and through the central aperture of the .revoluble table 9, is a sleeve lOt-he lower end of which is flanged as at 11 and bears against the under surface of the brace collar 6. The other or upper end of the sleeve extends a substantial distance above the table 9 as shown.

Mounted upon the table 9 is an upright frame indicated generally by the numeral 12. This frame comprises the two outer side bars 13 and 14 respectively the cross connecting top and bottom bars 15 and 16 and the vertical central bar 17 which is positioned midway between the bars 18 and 1e: and extends downwardly having its lower end 18 offset by the connecting portion 19. The central portion of the central bar 17 is thickened as indicated at 20 and this thickened portion is formed near its upper end to provide a bearing 21 which is directed toward a bearing 22 formed .uponand extended outwardly from the bar 13. The-lower end of the portion 20 is axially bored to set up a bearing 23 which is directed downwardly toward a co-acting bearing 2e formed in the lower cross bar-16 of the frame, directly therebene'ath. In this bearing 24: the upper end of the sleeve 10 is fixed as shown in Figure-3. Extending longitudinally through the center of the tower formed by the uprights 1, is a revoluble shaft 25 the upper portion of which extends through the sleeve 10, through the bearing 24; and terminating at its upper end in the bearing 28. Fixed about the upper end of this shaft 25 beneath the bearings 2st and 23, is a bevelled pinion gear 26 which bears against and revolves upon the upper face of the bearing 24. I

The lower end of this shaft 25 is mounted in a bearing 27 which is fixed to one of the lower brace members 2 and the shaft has fixed to its lower ends a bevelled gear 28.

Mounted in suitable bearings 29 at the lower portion of the tower is a horizontal shaft 30 the inner end of which has a bevelled gear 31 thereon which meshes with the bevelled gear 28, and the outer end may be provided with a pulley wheel 32 as shown I or with a gear or any other means which will enable one to take power from the shaft.

Mounted in the horizontal bearing 22 which is formed upon the vertical side bar 13 of the frame, is a horizontal shaft 33 which extends through this bearing 22 and has its inner end housed in the bearing 21. lu lounted upon and fixed to this shaft 33 between the bearings 21 and 22, is a bevelled gear 34 which meshes with the bevelled pinion gear 26 as shown.

Mounted upon the outer end of the shaft 33 is a wind wheel 35, fixed to the shaft to cause the revolution of the same when the wheel is revolved by the wind.

The frame 12 has formed at each lower corner thereof the foot pieces 36 by means of which it is secured by the bolts 37 to the table 9.

Extending laterally from one side of the frame 12 and from the central portion of the lower bar 16, is an arm 38 which is also down-turned at its outer end and secured to the flat form 9 by means of the bolt 39.

The vertical side bar 14 has formed there about the sleeve 40, which is of less length than the bar 14 and secured to the bar, by means of the bearing cap 41 and 42 respectively, are two arms 43 and 44. These arms extend outwardly a substantial distance from the frame as shown in Figure 1 and have secured therebetween by means of the space bars 45, the longitudinally extending slats 46 as shown in Figure 1. This structure constitutes the wind vane of the wind mill. As is clearly shown in Figure 4 the arm 44. has its inner end extended a substantial distance beyond the bar 14 to overlie and contact with the lower portion 18 of the central bar 17. This extended portion is indicated by the numeral 47.

Extending transversely of the top bar 15 of the frame is a swinging bar 48 pivotally secured intermediate its ends to the cross bar 15 by means of the bearing cap 49.

Mounted at one outer end of the bar 48 is an upstanding bracket 50 carrying a pulley wheel 51, and secured to and extending above the bar adjacent the bearing 49 is an upstanding plate 52 carrying a pulley wheel 53. The other end of the bar 48 has mounted thereon a shiftable weight and the bar is provided at a point between the weight and the bearin 49 with an eye bolt 55 having the eye upon the upper side of the bar, and between the bearing 49 and the bracket 50 is a second eye bolt 56 having the eye thereof upon the under side of the bar. Connecting the bolt 56 with an eye bolt 57 mounted upon the extended portion 47 of the bar 44 is a chain 58 which passes under an idler pulley 59 carried by the bracket 60 which is swivelly mounted in the end of the short arm 61 which forms a part of and extends from the portion 18 of the frame.

' Attached to the eye bolt 55 is chain 62 which passes over the elements 51 and 53 and extends downwardly alongside of and spaced from the uprights 1, to the lower portion of the tower where the end has secured thereto a weight indicated at 64. which latter serves to overcome the weight 54 when the chain 62 is pulled upon in a manner presently described.

The lower bar 44 of the vane is provided with an eye bolt 65 from which a spring 66 extends to a bolt 67 secured to the extended. arm 38 of the frame. This spring normally opposes the action of the weighted beam 48 to hold the vane in the wind.

As just stated the tendency of the bar 48 to hold the vane of the wind mill in the wind is controlled by the weight 54 mounted upon one end thereof which weight causes the opposite end to be normally extended upwardly thereby drawing upon the chain 58 which in turn pulls the extended port-ion 47 of the bar 44 over against the portion 18 of the frame 12 thus swinging the vane around to the prop-er'position to hold the wind wheel directly toward the wind. hen it is desired to stop the operation of the wind mill the chain 62 is pulled upon and drawn downwardly causing the weighted end of the bar 48 to be lifted thus slacking the chain 58. The spring 66 then comes into play and swings the vane around to a position transversely of the frame 12 thus causing the wind wheel to be swung with its edge turned toward the wind thereby stopping the operation of the wind mill.

Having thus described my invention what I claim is:

1. In a windmill of the character described, a supporting tower a turn table carried at the top of the tower. an arm fixed to the turn table and having a. threaded bearing, a tubular coupling element engaged centrally in the tower and in the threaded bearing, a substantially rectangular shaped frame integrally formed with the bearing and rising vertically from the turn table, a. wind vane pivotally connected to the vertical frame, a coiled tensioned spring connected with the vane and with said arm. a rocking beam swingingly supported above the frame and having a weighted end, a. flexible connection between said beam at a point removed from the weighted end and the wind vane, a wind wheel journaled in the frame and weighted flexible member connected with the rocking beam and guided over the end thereof remote from the weighted end of the same.
